The invention discloses a wall-attached connecting system for a building tower crane. The wall-attached connecting system comprises a tower crane body, a tensioning device, a transmission device and a positioning device, wherein one side of the tower crane body is fixedly connected with two groups of extending plates; clamping plates are arranged at opposite sides of the two groups of extending plates; one end of each clamping plate is equipped with a linkage rod; the tensioning device comprises a semi-threaded rod, a limiting block and a limiting slot; one end of the semi-threaded rod is fixedly connected with one end of the linkage rod; one side of the limiting block is fixedly connected with one end of the semi-threaded rod; the limiting slot is formed inside an external connecting rod; the transmission device is arranged inside the clamping plates; and the positioning device is arranged on a joint of the tower crane body and the extending plates. The wall-attached connecting system has the beneficial effects that: the tensioning device is utilized, a certain distance is formed between the clamping plates and the tower crane body, the clamping plates enter the extending plates without obstruction, and the tensioning device can drive the clamping plates to move, so that the clamping plates can completely enter the extending plates.

    本发明公开了建筑塔吊用的附墙连接系统,包括塔吊本体、张紧装置、传动装置和定位装置,塔吊本体的一侧固定连接有两组延伸板,两组延伸板相对的一侧均设置有卡接板,卡接板的一端设置有联动杆,张紧装置包括半螺纹杆、限位块和限位槽,半螺纹杆的一端与联动杆的一端固定连接,限位块的一侧与半螺纹杆的一端固定连接,限位槽开设于外接杆的内部,传动装置设置于卡接板的内部,定位装置设置于塔吊本体和延伸板的连接处。本发明的有益效果是:本发明利用张紧装置的设计,卡接板初始与塔吊本体存在一定的距离,卡接板进入到延伸板之间不存在阻碍,运行张紧装置可带动卡接板移动,以此保证卡接板能完全进到延伸板之间。
